Cyclopentenyle groups containing polysiloxane composition curable by UV to a thin layer.

摘要

Organopolysiloxane composition containing a cyclopentenyl residue crosslinkable as a thin layer on exposure to ultraviolet light, characterised in that it comprises: A. - 100 parts of diorganopolysiloxane containing at least 3 cyclopentenyl residues per molecule, each of these groups being directly bonded, via an SiC bond, to a different silicon atom, B. - an effective quantity of at least one photoinitiator. Application of the compositions to the production of coatings especially for the production of antiadhesive coatings on paper and for the encapsulation of printed circuits. p
